SUS304 stainless steel is a versatile, it is widely used to produce good overall performance (corrosion resistance and formability) of equipment and parts. 304 is the most widely used stainless steel, heat resistant steel. For food production equipment, and past chemical equipment, nuclear energy. Grade: SUS304 304 Specifications Chemical composition C Si Mn PS Cr Ni SUS304 ≤ 0.08 ≤ 1.00 ≤ 2.00 ≤ 0.045 ≤ 0.03 ≤ 18.0-20.00 ≤ 8.00-10.50 304 mechanical properties of mechanical performance specifications YS (kgf/mm2) TS (kgf / mm2) EL (%) Hv SUS304 ≥ 21 ≥ 53 ≥ 40 ≤ 200 - substantially austenitic steel, the most widely used; - excellent corrosion resistance and heat resistance; - mechanical strength and excellent low temperature properties; - - Single-phase austenite, non-hardening heat treatment (non-magnetic, temperature -196 ℃ - 800 ℃). - Tableware, kitchen, water heaters, boilers, bathtubs and pipe; - auto parts, muffler, windshield wipers and moldings; - medical equipment, building materials, chemical equipment, agricultural equipment, ship parts and electronic products. Stainless steel wire: also known as stainless steel wire, rod, plate element, but the stainless steel wire rope with different wire and screw the main spring wire line two, by definition: the screw line is mainly used for screws, and spring wire used to make springs Or other requirements of flexible metal products and other such light line, back line of hydrogen, electrolysis line, axle hairpin lines tensile strength of 1500-2000 has the hardness of the spring line are the following: all soft | 1 / 4 Hard | Semi-hard | 3/4 Hard | Full Hard | special hard rope Size: 7 * 1,6 * 12,7 * 7,7 * 19,17 * 39, etc., than the same material lines, rods, tubes. , plates to be expensive to the most expensive shares 7 * 7 Material: Domestic: 201 stainless steel rods, 301,304,321,316,316 L, 410,416,420,430 stainless steel rods, 431 and 309S, 310S, titanium, molybdenum, nickel, tungsten, chromium and other high temperature alloys. Imports: Korea 303F, 316F, 420J2, 430F stainless steel rods; Japan 303CU, 316LHS, 416F, 420F stainless steel rods; Uses: Widely used in chemical, petroleum, food, energy, power, aerospace, environmental protection, boiler heat exchanger art. Difficult to produce stainless steel corrosion, pitting, corrosion or wear. One of the highest strength material with metal or stainless steel construction materials. Because stainless steel has excellent corrosion resistance, so it can maintain a permanent structural components of the engineering design integrity. Chromium stainless steel is also set high mechanical strength and elongation in one, easy-to-parts manufacturing, to meet the needs of architects and structural designers. Precipitation hardening stainless steel. Has good formability and good weldability, high strength can be used as materials in the nuclear industry, aviation and aerospace industries. Components can be divided Cr (400 series), Cr-Ni system (300 series), Cr-Mn-Ni (200 series) and precipitation hardening (600 series). 200. Series - chromium - manganese - nickel austenitic stainless steel 300. Series - chromium - nickel austenitic stainless steel 301 - ductile, for formed products. It can also be rapidly hardened by mechanical processing. Good weldability. Abrasion resistance and fatigue strength than 304 stainless steel. 302 - 304 with corrosion resistance, due to the relatively high carbon intensity and therefore better. 303 - by adding a small amount of sulfur and phosphorus to more than 304 cutting. 304 - 18/8 stainless steel. GB grades for 06Cr19Ni10. 309 - 304 better temperature resistance. 316 - After 304, the second most widely used types of steel, mainly used in the food industry, the pharmaceutical industry and surgical equipment, adding Mo to obtain a special corrosion-resistant structure. Than the 304 because it has better resistance to chloride corrosion and thus as "marine steel" to use. SS316 is often used to fuel recovery. 18/10 stainless steel is usually in line with the application level. Model 321 - in addition to the added titanium reduces the risk of material other than the corrosion of the weld performance similar to 304. 347 - Add stable elements niobium, appliance parts for aviation and chemical welding equipment. 400. Series - ferritic and martensitic stainless steel. 408 - good heat resistance, corrosion resistance is weak, 11% Cr, 8% of Ni. 409 - the cheapest model (BAR), commonly used as automobile exhaust pipe, is a ferritic stainless steel (chrome steel). 410 - martensite (high-strength chrome steel), good wear resistance, corrosion resistance is poor. 416 - Adding sulfur to improve the processing performance of the material. 420 - "Cutting Class" martensitic steel, similar to Brandt's first high-chromium stainless steel this. Also used in surgical tools, can do very bright. 430 - ferritic stainless steel, decorative, such as for car accessories. Good formability, but heat resistance and corrosion resistance worse. 440 - high strength cutting tool steel, carbon is slightly higher, after appropriate heat treatment to obtain a higher yield strength, hardness can reach 58HRC, are among the most hard stainless steel. The most common application example is the "razor blades." There are three commonly used models: 440A, 440B, 440C, in addition to 440F (easy processing). 500. Series - resistant chromium alloy steel. 600. Series - martensitic precipitation hardening stainless steel. 630 - The most commonly used precipitation hardening stainless steel models, often called 17-4; 17% Cr, 4% Ni.
